Grape sorting

The technological concepts that have been developed for the Delta Vistalys optical sorting machine will give you valuable advantages and allow you to sort 100% of the grape harvest
according to your quality criteria.
The Delta Vistalys can reach a performance of up to 10 tonnes/hour and uses a colour camera to sort berries. Continual analysis of the pictures enables the operator to fine-tune the
sorting process extremely precisely to suit their own personal targets and the original quality of the grapes.

Function:

Before being sorted, 100% of the grape berries are transported onto a Delta TRV vibrating table (placed in front of the sorting machine) that removes the juice of the destemmed grapes
and feeds the Delta Vistalys at a constant rate.

A studded conveyor belt travels at a high and constant speed (2.5 m/s or 10 km/h). The berries are spread out and stabilised between the pimples which enables precise sorting to take
place at full speed. The pictures that are taken by the high speed colour camera are clear and precise thanks to the continual illumination of the berries and the shadow-free
backlighting from LEDs. The pictures can then be processed by a powerful computer that has been specially adapted to be used with grapes.

As soon as the pictures have been analysed, the unwanted parts are automatically removed by pneumatic high-frequency nozzles.
